  • Changes in Temperature, Ice, and CO2 During the Mid-Pleistocene Transition

    The recent Report by B. Hönisch et al. ("Atmospheric carbon dioxide concentration across the mid-Pleistocene transition," Reports, 19 June 2009, p. 1551) presented new data on CO2 over the past 2 million years (myr) based on Boron isotope measurements. The results are used to assess the role of CO2 during the Mid-Pleistocene Transition (MPT) about 1 myr ago, when the dominant glacial cyclicity cha...
